SEATTLE -- Getting high while seeing Seattle. Tourism entrepreneurs are making that happen.

It's been more than a month since retailers first started legally selling marijuana across Washington state. WeedBus.Club is an organization that allows passengers to get high on its sightseeing party bus.

"[People] love it," operator William Prigmore said. "They take pictures, they [give] thumbs up. It's great. We get a lot of positive feedback about the weed bus."

The bus' paint job sure makes what promises to be a mind-altering experience hard to miss. Betty Jo Jones, visiting from Montana, couldn't resist snapping a few pictures of the bus Tuesday morning along the Seattle waterfront.

"It's very unique," said Jones. "It's something I don't see every day."

Prigmore says that curiosity is what's driving business. On a Tuesday bus ride from Seattle's piers to SODO, some early-morning passengers took time to smoke during a short pit stop.

"They can smoke on the bus," explained Prigmore. "We go down to Cannabis City. They can buy it legally."

There is no divider separating the driver from the rows of smoke-filled fun. A risk of a second-hand high for the driver is drawing concern.

"Most of the time when they're smoking on the bus, we don't have drivers in there," said Prigmore.

The Seattle Police Department says it will monitor these tourism ventures.

Officers say passengers smoking pot is still considered public smoking, which is illegal. However, enforcing marijuana laws is the department's lowest priority, according to a police spokesperson.

The price for WeedBus.Club is $25 for an hour tour or a donation for passengers traveling a short distance. Prigmore says pot bus competition is heating up, so don't be surprised to see more of the new tourism vehicles on Seattle streets.
